This view will enable you to generate OpenOffice documents from templates written in OpenOffice 2.x

Just make sure that there is no OO tag in between your code (no change in formatting etc.). content.xml is a valid XML file, so you can do some preprocessing using xml.dom.minidom. I would also recommend caching (just save the zip file without content.xml and content.xml on its own).

HttpResponse can take file-likes directly: 

return http.HttpResponse(text)

thanks, I updated the snippet

Line 23 should probably use "odf_path" instead of "template_name".
